   Yes, please do.

Done.  This means we have to fiddle the pfinet glue-include stuff a
bit though, otherwise it won't compile anymore.  How about the
attached patch?  The put_cmsg() duplication is a bit odd, but we
should probably change the second one to do something useful.

        * glue-include/linux/socket.h (SOMAXCONN): Only define if it
        wasn't already.
        (msg_control, msg_controllen, struct cmsghdr, cmsg_len, cmsg_type,
        define if CMSG_DATA wasn't already defined.
